Occur Month Year

The Month and Year that the incident occured.

Occur Date

Date the incident occurred. The exact occur date is sometimes unknown. In most situations, the first possible date the crime could have occurred is used as the occur date. (For example, victims return home from a week-long vacation to find their home burglarized. The burglary could have occurred at any point during the week. The first date of their vacation would be listed as the occur date.)

Occur Time

Time the incident occured. The exact occur time is sometimes unknown. In most situations, the first possible time the crime could have occured is used as the occur time.The time is reported in the 24-hour clock format, with the first two digits representing hour (ranges from 00 to 23) and the second two digits representing minutes (ranges from 00 to 59).Note: By default, Microsoft Excel removes leading zeroes when importing data.
